مطالعه پایش محیطی یکپارچه در منطقه معدن بر اساس تجزیه و تحلیل تصویری

The mining area environment is a complex and dynamic system and is effected by mining activities. Therefore, knowing the dynamic change of the mining area environment is very important for mining and management of the mining area. But the traditional ground investigation always needs a lot of work and incomprehensive, it also takes a long period and lacks of real time. In recent years, the remote sensing monitoring method which has been applied widely to the mining area has been improved, but it still contains deficiencies, such as the singleness of the monitoring contents, the difficulties in the synthesized analysis of the new data with existing information. This paper integrates various remote sensing explanation methods and brings forward the concept about integrated environment monitoring in mining area based on image analysis, and discusses the strategy and technique of comprehensive information extracting, such as atmosphere pollution, earth covering and sinking, underground structure, etc.

Exploitation of mineral resources is usually accompanied by damage of environment and pollution. It is essential to know the environmental status of mining area to achieve “green exploitation” and to guide the production and the recovery after mining activities. Remote sensing has become a necessarily key method in monitoring and evaluation of the mining area because it is capable of gathering groundinformation promptly, fast, objectively and seasonally [1,2]. Mining has great effect on surrounding environment and it is complicated in space and time, involving the air, ground and underground. However, recent applications of remote sensing on monitoring of the environment of the mining area are only emphasized on limited fields and there are few researches which are from multiple directions, which mean that remote sensing is not fully employed. As remotely sensed imagery is developing towards high resolution, high spectral and multi-cycle, it is possible to make environment monitoring of mining area unidirectional based on photogrammetry and remote sensing.

Integrated environment remote sensing monitoring is the demand of “green mining”, it involves wildly and needs integrating multiplicate remote sensing data analysis methods. Although comprehensive environment remote sensing monitoring is still in the process of development and has a lot of problem to be deal with, it has well foreground and can resolve a lot of problem of mining area.
